Application filed January 17, 192D. Serial No. 352,098.

To all whom t may concern Be it known that l, Janes J. HnNNnssY, a citizen of the United States, residing at New York city, New York, have invented a certain new and useful improvement in Lubricators for Locomotive Journals, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being`- had to the accompanying drawings, formingpart of this specification.

My invention has relation to improve ments in locomotive journal lubricators, and consists in the novel details of construction more fully set forth in the specification and pointed out in the claims.

vThe invention relates particularly to lead truck and driving journal lubricators, and has for its object the provision of a lubricator as directly driven from the journal by means of cams or equivalent devices. f

A further object of the invention is to provide a duplex pump so constructed as to be directly driven by the cams dispensing with springs for the return movement or the plungers and further simplifying the construction so as to render the lubricator readily applied in a roundhouse.

Further and other objects are better apparentv from a detailed description of the in-y vention in connection with the accompanying drawings, in which,

Figure 1 is a vertical section lengthwise of the journal showing my lubricating device secured thereto. Y

Figure 2 is a vertical section through the journal box and cellar.

Figure 3 is a vertical section on the zig zag line 3 3 of Figure 1.

YFigure 4- is a horizontal section on the zigzag line 4 4 of Figure 1.

Figure 5 is a horizontal section on the line 5 5 of Figure 1.

Figure 6 is a face view of the cams and wedge rings assembled.

Figure 7 is a sectional detail on the line 7 7 of Figure 6.

Figure 8 is a face View of the tightening ring which holds the cams in place.

Figure 9 is al sectional detail on the line 9 9 of Figure 8.

Referring to the drawings, 1 is a lead or driving journal box provided with the usual brass 2 and cellar 3, and t represents the journal traversing said journal box. Positioned within the cellar 3 and beneath the journal l is a plate 5 between which and the journal is the waste lV whereby the journal isprovided with lubrication. The waste W is kept in contact with the journal t by means' of the coiled spring 6 which bears lightly against the bottom oi. the plate 5, thus forcing said plate toward the journal.

An oil reservoir R is secured to the cellar of the journal by means of bolts b, or can be integral, and within this reservoir are located the pumps consisting of plungers 7 7 operating within cylinders 8 8. The cylinders 8 are cast integrally with the pump reservoir, and beneath said cylinders is a port 9, said port 9 communicating with a second port 10, the latter port being located between the cellar 3 and pump cylinders. The lower edges of the cylinders 8 form a valve seat against which ball valves 11 11 are adapted to seat. The check valves are maintained in seated position by means of springs 12 12. The passage 10 is closed at its upper end by a block 13, and is provided at its lower end with a ball check valve 14, said ball 14 beingfmaintained in its'seated position by means ofa spring 15 which bears against the perforated stop 16 placed in the passageway 10 a sufficient distance yaway from the ball 141: to permit said ball to unseat. 'il he upper portions of the cylinders 8 are connected by a web "i7, said aveb being slotted to accommodate a leverI 18 pivoted on a pin 19, the ends oi said lever entering slots 20 20 in the plunger-s. Cams 21 are mounted on the joilrna] 4 above the plungers, said cams being formed in two pieces so as to be readily applied to the journal. The cams 21 are provided with cam faces a; near their outer edges, and with beveled faces 22 opposite the cam faces, which beveled faces are adapted to bear against wedge rings 23, each of which is formed in three pieces in order that they may be readily placed in position (see Figure 6). The cams are provided with screw threads opposite their inclined faces to receive retaining rings `24, the latter also being made in two sections to permit ready application. Each of said sections is provided with lugs 25 whereby said sections are secured together by means of bolts 26. From the foregoing, it

is readily apparent that the cams may be readily mounted on 'the journal without removing the journal.

lt is understood that 'when the `engine is running there is a certain amount of lateral movement of the journal, and in order to accommodate this movement the cam faces a ol' the cams are made wide enough so that said faces will remain in engagement with,

the plungers 7 notwithstanding such lateral movement.

The yengaging walls of the cellar 3 an reservoir R are provided with a port 29, said port communicating with the -cellar below the plate 5 'and with the 4chamber l() of the reservoir and a poi-t3() communicating with the cellar above the plate 5 and the reservoir. The cylinders 8 are provided with intake ports 31 through which the oil enters the cylinders from the reservoir.

The reservoir R- is 4provided with a cover 27 secured to said reservoir by means of bolts 28 so that the entire pump mechanism is enclosed.

It will be understood that a sufficient amount of oil is placed'i-n the reservoir. When the engine is running the journal 4 with the cams 2l will rapidly rotate, said cams alternately depressing plungers 7, one of which will be raised by the lever 18 when the other is depressed, which plungers in their downward movementwill force `the oil that has entered the cylinders vthroughvthe ports 3l past, the ball valves 1l andlla then up throughthepassage and port 29 into the celler 3 below the plate 5, cTheo-il will find its lway from here into the waste compartment, thus saturating the waste, andany surplus r'oil will, under the ,pump action, be -orced outwardly 4through the port 3Q back into lthe oil reservoir. It is understood that this actionfconti-nues so'long as the journal 4 is rotating, thus insuring a circulation of oil from the reservoir into the cellar andV through the waste back into the reservoir.

lt is obvious that the invention is susceptible of Inodiiications Ylialling within the spirit thereof and of which I wish to avail myself.

I claim:

1. In a journal lubricator, pump cylinders, slotted plu'ngers in said cylinders, a pivoted lever having spherical ends in said -slotsfor connecting said plungers, and 'means 'for falterna'tely depressing said connected plunger-s.

2. In a journal lubricator, a'pump, parallel plungers in said pump, a 'slotfin ea'oh of lsaid plungers, Va lever pivoted between said plungers to 4the pump "body "with its arms extending respectively into said slots, and means lfor alternately thrusting' said plungers in one direction.

A3. In combination with anen'g'i'ne jo'urnal, pumps adjacent thereto, camsgon "the journal, said cams being provided 'with bevel faces Ifor actuating Vthe pumps,- wedge rings enveloping the journal andV engaging the cams, and confining rings on-the outer ends of the cams.

l. In combination with an engine journal,

an oil reservoir, pump cylinders withinthe reservoir and communicating therewith, plungers in the cylinders, cams on the y,journal, said cams havingbevel faces for actuating the pumps, wedge 'rings enveloping the journal and engaging the cams, conlining `rings on the outer-ends of the cams and a `lever jpivotally mountedl between the plunfgers, the Aends of said *lever engaging'said plungers. n Y t In testimony whereof l lhereunto alli-X my signature this 12th day of January, M320.
